Values are the percentage in each category of the total number of clusters sampled. ANF, average number of fruit per cluster; ANAO, average number of abortive ovary per cluster; PAO, percentage of abortive ovaries per cluster; FS, fruit set as percentage of total number of pistillate flowers per plant. Values within the same column and year followed by different lowercase letters are significantly different at P ≤ 0.05 as indicated by LSD test.
